4-CH AHD1.0 4CH RX and 9-CH Audio Codec

4 CH AHD1.0 RX and 9 CH Audio CodecNVP6114 includes 4-Channel AHD1.0 RX and 9-Channel Audio Codec. 4-Channel AHD1.0 RX delivers high quality images. It accepts separate 4 CVBS/COMET/AHD1.0 inputs from Camera and the other video signal sources. It digitizes and decodes NTSC/PAL/COMET/AHD1.0 video signal into digital video components which represents 8-bit BT.656/BT.656like 4:2:2 byte interleave format with 27/36/54/72/108/144MHz multiplexed. NVP6114 includes Clock PLL, so 54/72/108/144MHz byte interleave function available. Especially, It is able to use same transmission cable with conventional one for COMET(SD level) and AHD 1.0 (HD level), and they provide the superior image quality by minimizing the interference when separating Y and C. 9-Channel Audio Codec is 8-Channel Voice/1-Channel Mic PCM Codec which handles voice band signals(300Hz~3400Hz) with 8bit/16bit linear PCM, 8bit G.711(u-law, a-law) PCM. Built-in audio controller can generate digital outputs for recording/mixing and accepts digital input for playback. 4-Channel Coaxial Communication Protocol communicates between controller(DVR) and camera on the video signal through coaxial cable.
